FEED-WATER REGULATOR.

SPECIFICATION forming part of Letters Patent N 0. 542,150, dated July 2, 1895.

Application filed March 4, 1 895.

To all whom it may concern.-

Be it known that I, MARCUS DOERHOEFER,

a citizen of the United States, and a residentof Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Feed-Water Regulators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a sectional view of the invention applied. Fig. 2 is a diagrammatic view of modi-.

fication. Fig. 3 is a fragmental sectional view illustrating change in regulator for modification.

The object of this invention is to provide means of simple and reliable character for regulating the supply of water to tanks or reservoirs-of different kinds, and especially.

to the feed-water-heating tanks or reservoirs of steam-boilers and to those tanks or reservoirs which supply water to other tanks which may be situated at the tops of build:

ings for the purpose of supplying water to I to prevent the overflow of the lower tank or reservoir, and to maintain a nearly constant Serial No. 540,470- (No model.)

Fig. 1. In the drawings, the letter A designates a closed water and steam tight chamber in which is placed a float B, which preferably consists of a hollow copper body or ball having at its lower portion a stem (1, which works in a suitable guide 17 at the lower portion of said chamber. 0 designates a smaller chamber, which is o'tfset from the upper portion of the chamber A, with which it communicates through a large opening 0 in-the wall of the latter. shell or casting of said chamber 0, which is attached to the shell of the chamber A in such a manner that it can be removed therefrom. At its outer end said shell D is formed with a valve-seat portion F. F is a chambered cap, which is secured to the outer end of said shell and within the chamber of which is a slide-valve F, which seats upon the outer face of said seat portion. G is a lever, which is pivotally connected with the float at g and which extends into the chamber 0, near the outer extremity of which itis fulcrumed at g. The extremity of the lever is loosely connected to the valve F, usually by forming on the lever a ball endf, which rolls ina socketf' of the valve and permits the latter a true movement on its seat. This connection is made through an opening in the seat portion F, which opening is closed by the valvein all positions of the latter. H indicates a feed-water-heating tank, which is connected with the float vessel or chamber A by means ofa pipe I, and with the valve-seat F by means of a second pipe J and port K, which opens into the valve chamber D through the valve-seat. K is a gage, by means of which the water-level in the floatvessel and in the tank H is indicated, the pipe I causing the same level to be maintained in both vessels.

The operation is as follows: When the tank H is filled, the float is raised to the position shown in Fig. 1, and the valve closes the port K, thereby shutting off all supply of water to said tank through the port K and pipe J. As the water falls in said tank the float also falls, and through the lever G moves the valve to uncover to a greater or less extent the port K and again admit water to said tank. It

D designates the will be readily understood without further description that a nearly-constant level of water will always be maintained in the tank, ihether the feed-pump be running fast or s ow.

I will now proceed to describe the second application of the invention above referred to and illustrated in Figs. 2and 3 of the drawings. L designates a large tank or reservoir, which is supplied with water from the wells L and pumps For other source through pipe L M designates a second tank, which is supposedly situated at the top of a building to which it supplies water, receiving its supply from the tank L through apipe M and pump M N is an overflow-pipe for the tank M. P designates the regulator, which is in all respects constructed the same as above described, with the exception that the port K and pipe Jcommunicate with the upper portion of the shell or casting I) and valve chamber D, instead of with the lower portion. For this. purpose the pipe E acts as a steampipe which is connected to a steam-boiler, (not shown,) while the pipe J leads to the steam-chest of the pump M The pipeI is connected to the tank L, as before.

The operation is as follows: When the tank L fills, the float is raised in the chamber A, and the port K (which has been closed) is by the movement of the valve F opened. Steam is now admitted into the pipe J to the pump M which is thereby set in operation to force water to the upper tank M. When the water falls in the tank L, the port K is again closed and the pump M stops.

It will be seen that in the arrangement shown in Fig. 1 the valve operates with a low level of water in the chamber A, whilein the arrangement shown in Fig. 3 it operates with a high level. In order to adapt the regulator to either of these actions, it is only necessary to attach the shell D to the shell of the main chamber in proper position, so that an ordinary mechanic can quickly convertt 5 the device from one arrangement to the other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a regulator for feed waterheating and other tanks, the combination of a float chamber, a smaller chamber otfset from the float chamber, the shell of said smaller chamber having a valve seat portion at its outer end, a chambered cap secured to said shell over said valve seat, a slide valve seated within the chamber of said cap, and seating against the outer face of said seat portion, an inlet to and an outlet from the chamber of said cap, the outlet port being controlled by the said valve, and a float-actuated lever connected t6 said valve through an opening in said seat portion, substantially as specified.

2. In a regulating device for feed water or other tanks, the combination of afloat vessel A, a shell D attached to the upper portion of said vessel and having achamber which communicates with the chamber of said vessel, said shell having a valve seat portion at its outer end, a chambered cap-piece secured to the outer end of said shell over said seat portion, a slide valve within the chamber of said cap and seating upon the outer face of said seat portion, an inlet leading into said chamber, an outlet leading therefrom through said seat portion, and a float-actuated lever extending through the chamber of the shell D, within which it is fulcrumed, and connected to said valve through an openingin said seat portion which is closed by said valve, said shell D being capable of reversal, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
